Operating with supplies from 1.4V up to 18V, these devices draw only 6.5µA, making them ideal for low voltage system monitoring. Hysteresis is included in the comparators, easing design requirements to insure stable output operation. The comparators each have one input available externally; the other inputs are connected internally to the reference. The comparator outputs are open collector and the output load can be referred to any voltage up to 18V (36V for LT6700HV), independent of supply voltage. The output stage sinking capability is guaranteed to be greater than 5mA over temperature. The three versions of this part differ by the polarity of the available comparator inputs. The LT...
